Specification of Letters Patent.

Patented Apr. a, 1918.

Application filed October 30, 1913, Serial No. 798,295. Renewed January 19, 1918. Serial No'. 212,836.

To all whom it may concern:

Be it known that I, Cnpiimus XV. Ensure, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Variable-Speed Mechanism for Sound and Pieture Reproducing Mechanism, of which the following is a specification.

I synchronous action both for sound recording and reproducing with a motion picture camera or projector mechanism; and the present.

structure is also designed for its use in recording sound records alone Where it is desired to employ a succession of, or a plurality of records to reproduce speeches, songs or plays.

Heretotfore in making sound records and reproducing the sounds-recorded thereupon -it has been impractical-to bring records into play-successively so that Where necessary a word or syllable might be cut or severed in two, a portion being impressed upon the preceding and a portion at the beginning of the succeeding record. By ,reason of this fact,

the size of the record has been limited, and the artist mustbe rehearsed previously to making the recordso as to insure the impressing of the full act, song or speech upon a single tablet, cylinder or disk. With the present invention, one tablet is operated at a time and the succeeding tablet is thrown in, to produce the desired successive action and to have recorded thereon without any interruption betweentho two tablets, exactly as if taken upon a single table, it being possible as before stated to cut a syllable so that a. portion thereof will be upon the preceding while the remaining portion will be upon the ture camera during the. production of the negative of the photograph In order to accomplish this result, it has been demonstrated that two record carriers are only necessary, for while one tablet is having sound recorded thereon, or the record is being reproduced, the next succeeding tablet to receive the record, or the record that is to be reproduced, may be manually placed upon the remaining record carrier, and the mechanism set for operation at the finish of the first tablet, the'first record carrier being brought to a halt and during the continued operation of the second, the third tablet or record being positioned for operation, etc.

It is also possible with the present mechanism, to operate in conjunction with ,a motion picture projector, and a single film, a

plurality of sound records, so that'the same are automatically connected to and disconnected from the projector mechanism, and where it is necessary, there is provided an interval between the operation of one record carrier and the next to permit of thepr'ojec- 'tion of titles, announcements and the like, upon the screen and through the instrumentality of the moving film. By this means, the film is permitted its desired movement at all times, it Thaving been demonstrated in practice, that with a 12 inch reel of film, five ten inch record disks, or injother words, five subjects may be visually dis,- played with the sound accompaniments.

With the foregoing and other objects in view which Will appear as the descriptionproceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can-be made Within the scope of what is claimed without depart ing from the spirit of the invention.

1 Referring to the drawings, the numeral 1 device is used as a recorder as shown in Fig.

1, may be driven from any form. of motor or from the camera mechanism of a motion picture projector (not shown), or as shown a in Fig. 3, from the projector mechanism P of a motion picture machine. A record plat- 85 form 5 is carried upon the upper end of the shaft 4 of each device, the/ upper end 6 of the shaft 4 being reduced and constituting the centering pin for the record tablet R, a second pin 7 being carried by the platform 5 and entering the record so as to hold the same fixed against independent rotation as the platform 5 is rotated.

As clearly illustrated in Figs. 1 and 2, and

in or r to complete the present mechanism both for recording and reproducing sounds, astylus guiding arm 8 is pivoted at 9 for swinging and slight longitudinal sliding .movement, its hooked terminal 10 being disposed to embrace and be held by the cens trally disposed cam 11 .carried by' the tablet so R, so that in the position as shown'in Fig. 1, the sound'box R may be placed so that the stylus thereof will seat within the stylus guiding kerf 12 of the member 8 to, at the proper time,' be freed, as the arm 8 is moved to the right, at the beginning of the phonic groove of the tablet R due to the cam action upon the member '8, said member 8 being automatically released and thrown from the position as shown at the left in Fig.' 1 to that shown at'the right'due to the engagement of the pin 7 at the opposite side of the member '8 asviewed at the left in Fig. 1. Thus the arm 8 is thrown out of the path of the rotating stylus and out of engagement with the cam 11. In the recording mechanism as shown in Fig. 1, the sound tubes 13 are connected to and carry their respective recorders R, a single conduit .14 with the sound directing conduit 15 being positioned as shown, 1t, however, merely being shown as indicative of any means whereby the sound ma be conveyed and impressed upon the tab et R, the various mechanisms required for maintaining the record soft not being 10:- illustrated.

As shown, the pivoted member 8 is provided with the switch closing terminal 17, which cooperates with the spaced spring terminals 18t0 close a circuit, the installation and purpose of which will presently appear.

As the mechanism for actuating each platform 5 is identical, the description of one will suffice for both. I

Fixed upon the shaft 4 within the casing 2 and below theplatform 5 is a sleeve 19, having the bridging portion 20 whgch carries the ring 21. Pivoted to the bridging portion 20 at diametrically opposite points,

are the two pawls or arms 22, the free ends of which are provided with the two teeth 23 and 24, whereby when the pawls move outwardly, the teeth 23 form the connecting link between theshaft carried clutch member 21 and the slow gradual speed clutch member 25, while the teeth 24 when the -pawls are moved inwardly, as will present appear, constitute a means for directly connecting the platform 5 to the driving shaft.

The member 25, as clearly illustrated in Figs. 6, l0 and 11, is counter-bored as at 26 to form a receptacle for the annular member 21 of the shaft carried clutch member and permit the same to freely rotate thereupon when the arms 22 are in neutral position. The central bore 27 of the member 25' fits rotatably upon the upper portion of the sleeve 28 whose ratchet teeth 29 are disposed to befin the same plane as the ratchet teeth 30 of the member'25, or in a plane to receive the teeth 24 of the arms 22 when the same are moved inwardly to the dotted line position, as shown in- Fig. 10, the ratchet teeth 30 being engaged as clearly shown in full lines in said figure, when the arms 22 are moved outwardly. The sleeve 28 is provided with the large pinion 31, which is rotated at all times by the drive shaft 3 through the worm gear 32 keyed upon said shaft 3. Thus, the sleeve 28 constitutes the member that is drivenat all times and rotates freely upon the lower end of the shaftv 4*within the support 2"0'f the casing.

The member 25 is provided with the peripheral gear teeth 33 which are the active transmission means, as will presently appear, when the pawls or arms 22 are in the full line position as shown in Fig. 10.

' rotated at a gradually increasing speed or In order to manually and automatically actuate the arms 22, to place them in operative engagement so that the platform 5 is at the maximum speed, or tolplace the arms 22in a neutral position, the two 1ncl1ned arms 34 are provided, one to each arm 22,

these arms being disposed to project within the annular recess 35 of the controlling memher 36. This member 36 i slidably mounted upon, the shaft 4 for movement to and from v the member 21, the same being counter-bored at 37 to receivethe truncated endof the sleeve 19 when the clutch members are in their lowermost position and the teeth 24 are in engagement with the ratchet teeth 29.

a A circumferential groove 38 is provided in ahe upper end of the member 36, .rried in tit) he frame 40 of the control lever 41. This ever is pivoted at its inner end in the post 42 rnd has its handle 43 projected through the- .lot 44 of the casing and in ready access to he operator.

In starting'the present mechanism, the lever 41 iselevated so that the same will rest in the upper recess 46 of the spring actuated 2 trigger lock 45, as clearly shown in Fig. 17.

The lever 41 at this time is in'the position, dotted line a of Fig. 17, at which time the member 36 is elevated with the pins 34 disposed in the lowerend of'the annular recess 35 With the arms 22 extended in the position as shown in Figs. 8 and 10; Thus the ratchet teeth 30 are connected so that as soon as the member 25 is rotated, the record carrier platform 5 will be rotated. When the lever 41 is in the dotted line position-Z), resting in the reis in central or neutral position and the arms 22 are disengaged both from the ratchet teeth 29 and 30. W hen the lever 41 assumes the lowermost position as shown in full lines Fig. 17 and as clearly illustrated in Fig. 6, the arms 34 are seated well within the recess 35 of the member 36 and consequently the arms are moved to dotted line position as shown in Fig. 10 with theteeth 24 in engagement with the ratchet teeth 29 of the member 28, and as the member 28 is driven di-v rectly from the shaft 3 through the w'orm 32 and gear 31, the record carrier platform 5 is thus rotated at themaximum speed.

Carried by the lever 41 between the shaft 4 and the free end thereof, is a lip or projection 48, the purpose of which as clearly shown in Figs. 18 and 19, is to permit'of the closing and opening of the switch members 49 and 50, the purpose of'which will presentlyappcar in the detailed description of the electrical installation. The switch 4950, as clearly shown in Fig. 19., however, will be closed when the lever 41 is in the ele vated position or the position a of Fig. 17, being opened when the same is released by the member 58, as will presently appear to, permit the lever 41 to assume the full line position Fig. 17 and also as clearly illustrated in Fig. 18. The switch members 49 and 50 are insulated from each other and are connected to and supported by thefpost 51 within the casing.

Mounted freely upon the shaft 3 is a 100 clutch member 52, which is provided with the. worm gear 53, said worm gear 53 being in mesh at all times withthe gear 54 which; is mounted at 55 in the casing for rotation, said gear carrying the cam 56, which is 105 adapted to engage the anti-frictional roller pin 57 carried by the member 58. This member 58 is pivoted for swinging movement at 59, so that its toothed segmentGO, which is in mesh at all times with the gear 110 teeth 33 of the member 25 will be moved fromthe position as shown in Fig. 4 to that shown in Fig. 5 and consequently impart rotation to the member 25. and through the pawls or arms 22, which are at that time in member 21 to the shaft 4 and platform'5.

The cam 56 isvso constructed,- that the first movement imparted thereto will gradually move the segment 60 so that a slow speed will be imparted through the members 25 and 21 to the shaft 4, said speed gradually increasing, as the segment 60 approaches its extreme position, as shown in Fig. '5 and .125 previous to its release by the cam 56 to be returned by the spring 61. The segment h 60 is limited in its return movement by' means of the pin 62 mounted in the casing.

When the segment 60 was primarily started by the cam 56, the platform 5, as justde.

scribed was gradually started from a stand still and rotated through the medium of the segment 60. As the trigger latch .45 is in the path of the member 58, such member 58 simultaneously with the engagement of the pin 68 with the' clutch member throwing arm 65, engaged the trigger latch 45 so that the lever 41 was released from its upper position a to its lower position, thus permittin the clutch actuating member 36 to descen and retract the pawls 22 so as to disengage the teeth 23 from the ratchet 30 of the member 25 and engage the teeth 24 ,with the teeth 29 of the high or maximum speed actuating clutch member 28.

In order that the gear 54 may be'automatically operated or connected to the shaft 3 through the clutch 52 a slidably mounted clutch member 63 is splined upon the shaft 3 and is controlled by means of the yol se 64 cargied by the lever 65, said lever 65 being provided with the armature 66- dispose'cl'gto be influenced in adirection to engage the clutch 63 with the clutch 52 when the electromagnet 67 is energized, the circuit to said electromagnet 67 being completed upon the positioning-of the lever 41 in the notch 46 when the switch members 49 and .50 are closed as illustrated in Fig. 19.

As before described when the pin 68 assumes the position as shown in Fig. 5, the clutch throwing lever 65 is operated and the clutch member 63 is released from the member 52 so that the shaft 3 will rotate freely within the member 52 without transmitting motion to the gear 54 and cam 56.

In order to lock the lever 41 in its lowermost position with the clutch members 28 and 21 driving the shaft 4 and platform 5, and thus during the recording or reproducing of the record, a bell crank lever 69 is pivoted in the free end of the lever 41 andhas its hooked terminal disposed to engage the lug 71 of the casing 2, said hooked terminal 70 being manually released by means of the handle 7 2.

It f is thus evident from the foregoing,

that the operator in starting the present mechanism, manually elevates the lever 41 to be automatically engaged by the catch 45 and maintained in.the uppermost position, such action closing the switch @members 49 and 50 and thus permitting the actuation at the proper time of the electromagnet 67 and its armature controlled lever 65 to throw the clutch member 63. Thus, as Wlll pres-' the energiz'ation of the electhe shaft/'3 being continually the clutch member 63 to ently appear, tromagnet 67 rotated, will cause engage'the clutch member 52 and through the gear 54 and cam 56 the segment 60 Wlll be swung so that the same will impart a slow 'radually increasing movement through the c utch members 21 and 25 to the shaft 4 and record platform5. The cam 56, due

to its peculiar shape, will cause a gradually increasing speed to be imparted to the seganent '60, thus bringing the platform 5 from .an inert condition to the desired speed at the time when the pin 68 engages the clutch actuating lever 65 and the member 58 en gages the spring actuated latch 45 to permit the lever 41 to fall to its lowermost position. Thus simultaneously with the disconnection of the clutch 63 from its 005perating member 52, the movement of the arms 22 from the full to dotted line position in Fig. 10 there will be a direct connection of the clutch member 28 through its gear 31 and the worm 32 of the shaft 3 to the record carrier platform 5.

' In practice, the distance of rotation imparted by the segment 60 is approximately two-thirds 4' and :record carrier 5, so that the stylus guided by the stylus guiding portion 12 of the member 8 will, due to the rotation of the record tablet R and its cam 11 impart the desired movement to the stylus so as to deliver the stylus into the beginning of the phonic groove. As the record carrier is moved at a gradually increasing speed, there is no danger of the stylus being pulled or jumped into any other point of the phonic groove, this peculiar arrangement providmg a-means to insure the proper introduction of the stylus into the groove and at the beginning of the sound reproducing portion thereof simultaneously with the release of the clutch member 63, and the connection of the clutch member 21 with the clutch member 28, said member 28 as before described being continuously rotated through the shaft 3 and the wormgear 32. r

As before stated when the lever 41 was released from its upper dotted position a to the-lower full line position Fig. 17, the lug 48 was also lowered and thus permitted the opening of the switch members 49 and 50 and the consequent opening of the circuit to the electromagnet 67 so that no accidental energization of such electromagnet could take place until the lever 41. was again manually elevated to its uppermost position.

After the playing or completing of the record, the operator grips the lever by the handle 43 and releases the catch 69 so that the lever may be positioned in the intermediate dotted line position b Fig. .17, the clutch member 21 due to the intermediate position of the actuating member 36 having its arms 22 neutral, while the record just recorded or reproduced may be removed from its platform 5 and the next tablet placed thereupon. After the proper posito a full revolution of the shaft.

tioning of the record and the arm 8, the

themes 7 i v the lug 48 closes the switch members 49 and 50. v

When the cam 56 as before described, has moved-to a slightly farther distance than that shown in Fig. 5; or when the apex thereof has passed the pin 57, the segment 60 is released to the action of its spring 61 so that the parts are then returned to their normal position, 'as clearly shown in Fig. l. 10 As the member 25 at that time, is released,

the same is freely rotated in the reverse direction by the segment 60 when returning from its extreme position.

In order to fully describe theoperation of reproducing with the present. mechanism and the installationas shown in Figs. 3 and 7, and wherein the transmitters "R and R are electrical transmitters for operation from the records carried by the respective mechanisms A. and B, it is preferable that the current be taken from the direct cur rent lines 75 and 75 and led to the present sound reproducing mechanism by means of the switch S. In this form of transmitter, conductors 76 and 76 are led to thetact the respective metal strips 78 at all times are the metal strips 80 and 80, these being disposed to be in the same place so that the respective contact plates 7777 will be properly electrically connected to the conductors 81-81 so that current is roperly delivered from the mains 7 5 and 5 through the resistance lamps L'L and the transmitters R or B so that the sound reproduced bythe phonic groove upon the record being actuated and the respective transmitter, will be amplified and directed to the desired point by means of the amplifier or receiver 200. V

- It is essential that the member 79 be prop- 56 erly controlled so as to-insure of the proper transmitter being active and yet at the same time it is undesiralole'fo complete the elec' trical circuit with the transmitter and its amplifier 200 previous to the placing of the stylus into the sound reproducing portion of the record. To this end, the switch memhers 17 and 18 of the respective mechanisms A and B are provided.

Thus with the parts in the. position as 60 shown in Fig. 7, the arm 8 is in the position to receive the stylus of the transmitter in the directing kerf 12, the lever ll beingelevatcd so that the switch members 49 and 50 are closed, and the record being in the position to now be started or rotated. As before stated,'the rotation of the record due to the cam 11 will pull the arm or member 8 inwardly and direct the stylus of the transmitter into the phonic groove so that whenthe pin 7 has moved from the position at the rear of the arm 8 and engages the same upon. the opposite side, the arm 8 will be thrown from the position as shown at machine A in Fig. 7 to that shown in the machine at B. The arm 8 being assisted in this movement by means of the spring 8 will place the switch closing member 17, which is insulated from the arm 8 to close the switch 18, and assuming that the record in the machine Bis rotating, the following circuit to energize the electromagnet 84 is formed: The ground 87 which is connected to the casing 2, the switchmembers l7 and 18, the conductor 88, the electromagnet 84,

the conductor 89, the battery 90, and the conductor 91 which is grounded on the casing 2. Thus the electromagnet will operate the core 83 to move the lever 82 to the position as shown in Fig. 7, and thus rotate the switch 79, so that the contact plates 7777 of the transmitter It will engage the plates 78, and through the plates 80 and 80 connect the transmitter R in circuit with the current mains 7 5 and 75. Thus, the telephonic circuit is closed and as the record of the ma- 95 chine or mechanism B is being rotated, the sound produced in the transmitter R will be repeated in the amplifieror receiver 200'. This receiver 200 is disposed in practice at any desired pointwithin the theater or .building,'and' any number may be placed in circuit as may be deemednecessaryl The switch members 17 and 18 of the mechanism A are disposed to energize the electromagnet 85 through a circuit including the battery '90, the conductor 91, the casing 2, theconductor 87, the switch members 17 and 18, the conductor 88, the electromagnet 85, and the conductor 89.' Thus when the mechanism A is in the position as shown in Fig. 2, the switch 79 will be moved in the opposite direction so that the transmitter R will be connected in the telephonic circuit.

In order to insure the automatic energizw tron of the electromagnet 67, the two film actuated switch members 92 and 92 are provided. The switch members 49 and 50 are closed when the lever l1 is elevated as previously described, and consequently automatically connects the elected or selected record carrier, through the instrumentality of a moving film (not shown) of the mo.- tion picture projector mechanism P. A button or other means upon the film (not shown) which will cause the movement of its respective switch member 92 or 92' into closing relation with the switch points 92%:93 is carried by the film and at the desired predetermined points will permit of the proper connecting of the selected record 30 with the shaft 3 and consequently the projector mechanism.

When the switch as 92-93was closed by the film as just described, the circuit completed included the battery 90, the conductor 91, the casing 2, the conductor-97, the switch members 50 and 49, the electromagnet 67 and the conductor 95. Thus the electromagnet 67 at the elected or selected reproducing mechanism here illustrated in 1 r Fig. 7 as the mechanism B, is energized,"

and consequently actuates the clutch throw ing lever 65 to throw the clutch member 63 and consequently operate through the gear 54 and the cam 58 of the segment 60, to thus gradually start the record of the mechanism B from its inert condition to gradually increased speed until finally the record carrier is connected through the clutch members 21 and 28 to the shaft 3. The opening of the circuitcontrolling the electromagnet 67 to prevent any danger of the renergization of the electromagnet 67 was caused by the falling of the lever 41 when the catch .45 was released by the member 58. Y The' switch members 49 and 50 of the mechanism A were manually set by the elevation of the lever 41 and the closed switch 1718 is opened manually by the operator when the record on the mechanism B has reached its end, and just previous to the closing of the switch 92-93' by the selected button carried by the film and thus consequently'previous to the energization of the electromagnet 67 of the mechanism A through the cir cuit including the battery 90, the conductor.

91, the casing 2, the conductor 97 the switch members 50 and 49, the conductor 90, the electroma'gnet 67, the conductor 95", the switch 9293 and the conductors 94 and 94. 1'

It will thus be seen from the foregoing, that with the present installation, both mechanical and electrical, that the complete mechanism both for recording sound either independently of or in synchronism with a motion picture camera, is permissible, while the complete control of the present apparatus for reproducing sound from a projector mechanism as per the mechanisms A and B is provided for.

It is also apparent that by the manipulaw tion of the records from one carrier to the other, that complete plays, operas or the like -without the reproduction of the scene. i
